Quasi cw laser action has been achieved at several wavelengths near 308 nm in an electron-beam excited supersonic flow at very low temperature and high density. The 0--1, 0--2, and 0--3 XeCl laser emissions have been obtained when Ne/Xe/HCl mixtures aerodynamically cooled to 120 K and at a density up to 1.7 amagat were excited by an electron beam of medium intensity (j/sub eb/approx. =10 A cm/sup -2/, 600 ns). Up to 15 mj of laser energy (approx. =1 J/l) was extracted in 500-ns pulses from the 16-cm long and 1-cm-diam useful volume of this laser. The highest intrinsic efficiency (laser energy out / e-beam energy deposited in the active medium) observed was over 2.5%.
